摘要

厌氧/好氧(A/O)膜生物反应器(MBR)工艺是在MBR技术基础上发展起来的一种有效的污水处理方法。本文对A/O MBR系统的两个主要运行指标进行了研究和优化。最终结果表明，在缺氧区与好氧区HRT比为1:3(本系统为:好氧区4.5h，缺氧区1.5h)、IR率为300%Q的运行条件下，COD、NH3和TN的去除效果最好。优化后的系统出水COD低于30mg/L;NH3-N保持在10mg/L以下;TN < 40mg/L。出水达到中水回用标准

A Pilot Study on Domestic Wastewater Treatment with A/O MBR Systems

Anoxic/aerobic (A/O) membrane bioreactor (MBR) process, which is based on the MBR technic, is an effective method of wastewater treatment. In this study, two chief operation indexes of A/O MBR system are studied and optimized. The final results shows that, under the operation condition that the HRT rate between anoxic and aerobic zone is 1:3 (which in this system is: 4.5h in aerobic zone, 1.5h in anoxic zone), and the IR rate is 300%Q, the COD, NH3 and TN removal effects reach the best. In the optimized system, the COD of effluent is below 30mg/L; NH3-N is kept lower than 10mg/L; and TN is lower than 40mg/L. the effluent reaches the standards of water reuse
